You might get a more informative answer if you ask this in the Installation and Configuration forum or the General Discussion forum.

But all your questions are answered in the Intercommunications multi-platform manual for Websphere MQSeries available through the button labeled 'Documentation' at the top of this page.

I'll try to give some brief answers. Like Jeff said, you'll get all sorts of details in the intercommunication manual. You can also find things by searching this site.

1) A channel listener (runmqlsr, amqcrsta) is a program that accepts tcp/ip requests and gets them routed into the qmgr.
2) A channel listener is either started from a command line/service (runmqlsr) or via inetd (amqcrsta).
3) You need a channel listener any time that you are trying to connect your applications in client mode instead of bindings mode. You also need one if you are trying to do qmgr to qmgr communication (remote messaging).
4) I'm not sure that there is a limit. It is probably dependent on the operating system. Each listener does listen on a specific port.
